Help me. I'm new. Neither of which I do not know at all. I bought the VPS server for the first time. I absolutely do not know how to connect and configure the server. Please tell me which version of UBANTU is better to choose and Node js. And how to set it up. I would like to configure the server and using node.js with socket.io for instant chat application.
When it comes to Ubuntu, I normally recommend the latest LTS (long-term support) release. That'd be 16.04 as of right now :-).
To get you started, I'd recommend the following guide which covers NodeJS installation on 16.04:

In terms of connecting to your Droplet, you'd need to use a terminal emulator such as PuTTy (on Windows and Linux) or the Terminal application on MacOS.
If you've never used PuTTy, I'd check out:
On MacOS, you'd open Terminal and run:
ssh root@ip
Where ip is your Droplet IP. You'd then be prompted for your root password.
I did not think that there would be such an instant help! Thanks for the advice! I will try.
